Inaccurate file size report with du?

This is really strange... my system's du is reporting file size smaller than it really is... and it is only happening on one of Solaris 10 I have...

Code:

#ls -lrt tracks.txt
-rw-r--r--   1 oracle   oinstall 2166525362 May 16 03:32 tracks.txt

# du -k tracks.txt
953805  tracks.txt

# du -h tracks.txt
 931M   tracks.txt

Reports the same from global to non-global zones of this box

Code:

#ls -lrt tracks.txt
-rw-r--r--   1 user      user      2166525362 May 16 16:34 tracks.txt

#du -k tracks.txt
2126577 tracks.txt

#du -h tracks.txt
 2.0G   tracks.txt

Reports correct on a different box running same version of Solaris and from what I can tell.. same "du" binary

Code:

#ls -lrt tracks.txt
-rw-r--r-- 1 backup backup 2166525362 May 16 16:16 tracks.txt

#du -k tracks.txt
2115752 tracks.txt

#du -h tracks.txt
2.1G    tracks.txt

Copied it to a ubuntu 12.04.. reports correctly at about 2.0G

Any insight?? Thanks!!!!

It's the zfs.... not sure why it is reporting inaccurate file size though....

On the problematic box... global zone:

Code:

# ls -lrt tracks.txt
-rw-r--r--   1 105      101      2166525362 May 16 03:32 tracks.txt

# ls -lrt /export/home/tracks.txt
-rw-r--r--   1 root     root     2166525362 May 16 17:24 /export/home/tracks.txt

# du -h tracks.txt
 931M   tracks.txt

# du -h /export/home/tracks.txt
 2.0G   /export/home/tracks.txt

file in the local directory and file in "/export/home" is the same size..
but du reports different sizes...
local directory is a ZFS mount
